Sadly, I think this answers my own question....
What are broker “non-votes”?
Broker non-votes occur when nominees, such as banks and brokers holding shares on behalf of beneficial owners, do not receive voting instructions from the beneficial holders at least ten days before the meeting. If that happens, the nominees may vote those shares only on matters deemed "routine" by the New York Stock Exchange (“NYSE”), such as the ratification of auditors. Nominees cannot vote on non-routine matters unless they receive voting instructions from beneficial holders, resulting in so-called "broker non-votes." The effect of “broker non-votes” on each of the proposals that will be considered at the Annual Meeting is described below and in our proxy statement.
The election of directors is not considered to be a "routine" matter and brokers are no longer permitted to vote in the election of directors if the broker has not received instructions from the beneficial owner. Accordingly, it is particularly important that beneficial owners instruct their brokers how they wish to vote their shares.
We believe that the proposal for the ratification of our independent registered public accounting firm is considered to be a "routine" matter, and hence we do not expect that there will be a significant number of “broker non-votes” on such proposal.
The proposals to: elect directors, and approve, on an advisory basis, the compensation of the named executive officers are non-routine and the record owner may not vote your shares on either of these proposals if it does not get instructions from you. If you do not provide voting instructions on these two matters, a broker non-vote will occur. Broker non-votes, as well as “ABSTAIN” votes, will each be counted towards the presence of a quorum but will not be counted towards the vote total for any Proposal, other than Proposal No. 2.
